Understanding predictors of change in a day treatment setting for non-suicidal self-injury.

OBJECTIVES: To examine change in non-suicidal self-injury (NSSI) frequency, quality of life, and functional impairment from admission to discharge in patients enrolled in partial hospitalization and intensive outpatient programmes (PHP/IOP) designed to treat NSSI. Demographic, clinical, and treatment-related predictors of changes were also examined. DESIGN: Data were collected as part of routine clinical assessment procedures at admission and discharge from patients enrolled in a PHP/IOP programme designed to treat NSSI. The clinical assessment included measures examining quality of life, functional impairment, and NSSI behaviour. METHODS: Paired t-tests were used to examine change in NSSI frequency, quality of life, and functional impairment. Reliable clinical change analyses were used to identify clinically significant change in quality of life and functional impairment. Multilevel mixed-effects regression was used to examine predictors of change for quality of life and functional impairment. Negative binomial regression was used to examine predictors of change for NSSI frequency. RESULTS: From admission to discharge, NSSI frequency significantly decreased and quality of life and functional impairment evidenced clinically significant change. Age, race/ethnicity, and insurance type predicted change in functional impairment, while gender predicted change in quality of life. Urge to self-injure predicted change in NSSI frequency. Borderline symptoms predicted change across all outcome variables. CONCLUSIONS: Patients who completed a day treatment programme for NSSI evidenced significant change in NSSI frequency, functional impairment, and quality of life at discharge; however, several demographic and clinical variables were associated with change. PRACTITIONER POINTS: Patients who engage in NSSI show significant change from admission to discharge in a day treatment programme dedicated to the treatment of NSSI. Quality of life and functional impairment are important outcome variables to consider and evaluate in higher levels of care. It is important to consider demographic and clinical variables when creating a treatment plan for NSSI. Although BPD symptoms may be important to consider in day treatment for NSSI, interpersonal dysfunction, depressive symptoms, and mood lability may also affect change in symptoms.

Moderators of treatment outcomes in a partial hospitalization and intensive outpatient program for eating disorders.

Eating disorders cause a number of severely impairing symptoms that may require more intensive intervention that is available through outpatient therapy services. The PHP/IOP level of care may be an effective mode of treatment in these cases, but few studies have examined overall outcomes or treatment moderators for this level of care. Using a large sample from a PHP/IOP specifically designed for the treatment of eating disorders, the current study examines a variety of symptoms (eating disorder severity, quality of life, depression, etc.) from admission to discharge, as well as potential moderators of treatment, including demographic and clinical factors. Overall, the PHP/IOP level of care was found to improve treatment outcomes. Age, race, gender, and depression were found to moderate the change in quality of life and functional impairment. Additionally, patients diagnosed with anorexia nervosa had significantly lowered quality of life and greater eating disorder symptomatology than all other diagnoses. The results of this study can help to inform clinical practice and help guide in treatment decisions at the partial hospitalization level of care.

Characterizing gender differences in nonsuicidal self-injury: Evidence from a large clinical sample of adolescents and adults.

While nonsuicidal self-injury (NSSI) is common in both men and women, research exploring the intersection of NSSI and gender has been limited by the use of small samples of males drawn primarily from non-clinical populations. To address these limitations, we analyzed data from a large sample of patients enrolled in an NSSI partial hospitalization program (PHP) to compare males and females across several variables, including NSSI characteristics, correlates, and pre-post treatment outcomes. Results indicated similar NSSI characteristics and treatment outcomes for males and females, with few exceptions. Males notably reported lower severity levels for most NSSI correlates (e.g., psychopathology, suicidality), highlighting the need to screen males for NSSI even when reporting comparatively less impairment. Finally, our results also suggest that PHP treatment for NSSI can be beneficial for both males and females. These findings have implications for the assessment, diagnosis, conceptualization, and treatment of NSSI in males and females.

Emotional reactivity in a clinical sample of patients with eating disorders and nonsuicidal self-injury.

Emotional reactivity is theorized to contribute to both eating disorders (ED) and nonsuicidal self-injury (NSSI). Although EDs and NSSI frequently co-occur, no study has examined emotional reactivity in individuals with both conditions. This study examined the following hypotheses in a large clinical sample (N = 648): (1) patients with co-occurring ED and NSSI would report higher emotional reactivity and more severe clinical characteristics; (2) among those with EDs, patients with bulimia nervosa (BN) would be more likely to report NSSI and evidence higher emotional reactivity compared to those with anorexia nervosa (AN); and (3) higher emotional reactivity would be associated with worse treatment outcomes. Data were collected at admission and discharge from inpatient, partial hospitalization, and intensive outpatient treatment programs for EDs or NSSI. The NSSI-only and co-occurring groups reported significantly higher emotional reactivity than the ED-only group. Among those with EDs, individuals with BN reported higher emotional reactivity and were more likely to engage in NSSI compared to those with AN. Emotional reactivity was inconsistently related to treatment outcomes among the co-occurring and ED-only groups. In sum, results highlight the importance of emotional reactivity in clinical presentations, particularly when NSSI is present.
